Another instance is when an operating system has serious issues; in this case erasing and installing a “clean” copy of Mac OS X may resolve the situation. The reasons to repartition your system drive are a bit more complex, so they are covered in the next section. Nevertheless, the process of repartitioning your system drive can also effectively erase previous data, and thus is generally done prior to installing Mac OS X. You will use Disk Utility both for erasing and repartitioning the disk. Disk Utility can be found on any Mac in the /Applications/Utilities folder or, as covered previously, from the Utilities menu when started up from the Mac OS X Install DVD.

Apple also introduced a dynamic installation package that remains up to date as long as the Mac has Internet access. Network-based installation packages automatically download the latest software from a vendor’s servers during the installation process. Finally, Apple increased the security and reliability of software installation packages by supporting signed packages. These packages contain special code used to validate the authenticity and completeness of the software during installation. This makes it nearly impossible for nefarious hackers to insert illegitimate files in trusted installation packages.

In fact, many applications require only that the user copy a single application file to the local system drive. At the same time, more complicated software may require multiple resources placed at a variety of specific locations on your Mac. A prime example of a complicated software installation is any Mac OS X system software update. The Installer application makes complicated application installations simple.
